Hypothesis 
My hypothesis is that the grass will not be as damaged as the lettuce after I put it into the freezer. I think that the lettuce is more vulnerable to the cold, harsh weather. 

  Abstract 
       I have done this experiment to see if frost damages temperate plants. In the process of completing this experiment, I also wanted to figure out which plant would be more damaged. Would the grass be damaged more than the lettuce or would the lettuce be damaged more than the grass? I also wanted to figure out by how much the plant is damaged and why it was damaged the way it was. 
     I completed this experiment by following these simple steps. The first thing I did was pick some grass and I put it in a pie pan. Then, I took a head of lettuce and I put that into a pie pan. I then put both of the pie pans in the freezer at the same time for ten minutes. After ten minutes, I took the pie pans out of the freezer and I observed the two plants. I wrote down my observations, my results, and my conclusion. 
      The results of the experiment turned out that the lettuce was damaged more than the grass. The color of the lettuce faded and the lettuce itself was harder than the grass. The texture of the grass was also much smoother than the texture of the lettuce. The grass turned out to be more adaptive to the harsh, cold weather. These are the reasons why I did the experiment, the procedure I used to complete this experiment, and the results of my experiment. 

 
 
 

Materials   
  •  Two pie pans
  • Grass 
  • A head of lettuce 
  • A  freezer 
  • A pen 
  • Some paper

Procedure   

1. I will pick some grass and put it in a pie pan.
2. I will take a head of lettuce and put it in a separate pie pan.  
3. I will put both of the pie pans in the freezer at the same time for ten    minutes. 
4. After ten minutes, I will take the two pie pans out of the freezer and write my observations. I will also write down my results and my conclusion. 
Results   
 
This graph shows the amount of damage that the grass had according to my observations. The numbers on  left hand side of the graph represent a scale I developed myself to detect damage. 


This graph shows the amount of damage that the lettuce had according to my observations. The numbers on  left hand side of the graph represent a scale I developed myself to detect damage.

Conclusion 
 In conclusion, I have found out that according to the texture, color, and hardness or softness, that the lettuce was more damaged than the grass. The color of the lettuce faded while it was also much harder than the grass. The texture was also not as smooth. This is why the lettuce was more damaged than the grass.
